To all wko-m t may concern:

Be it known that I, donn F. .Srnnnrsrna citizen of the United States, residing Vat l/Vin-throp, in the countyo Suffolk and State .ci Massachusetts, have` invented cer'- tain Improvements in the Art ot` attaching Heels, ot which the following description, in connection Withthe accompanying drawings, is a specilication, like reference charactersl on the drawings `indicating lilre part-s in the several ligures. v

This invention relates to the `attachment of heels to shoes, it concerning particularly the securing ot such yieldahle heels as.those ot' rubber, which .liave, .prior toit-heir' att-aclnnent, a concave term. 1

A. Well-known practice in connection with themachineenailing oi rubber heels involves Surrounding the heel with a no provided with an opening into v. i heel substantially tits, sorthat it is prevented from expanding laterally under the pressure which is applied 4in `the heeler.` '.lliis prevents the deformation et lthe heel the consequent carrying of the `nailereceivijng openings and Washers out of alinement with the Qpenings in the die-block of thenpparatus.` Vilhcn, however, such` a procedure is app-lied `to the concave type ot heels, ot' which there are `several slightly differing forms in use,l dithculties arise. These heels are usually concavoconvex. having a depression at the side which is to contact with the outer surface of the heel-hasaand being correspondingly rounded outwardly at the tread-face. These heels, in attachment, are lia'ttened under pressure npon their leases, to bring the inner and outer surfaces into sahstantial parallelismand produce, close con-,- tact hetWeenthe peripheraledge olthe heel and the hase. lit such a heel :loe conlincd closely in the ring previously mentioned, laclrot opportunity to expand` prevents its flattening, and interferes with its proper application.` It, on the other hand, some lateralplay ot thehecl is permitted in the ring, it` `ivill not` helocated dehlnitely,` and its openings may not he alined correctly with the drivers. The present `invrmtion overcomes such ditliciilties hy a novel method di procedfureand adevi'ce Afor use in carrying out this-method.V

Broadly considered, my improved method comprises the steps of relatively7 positioning a heelandfthe receiving surface ot the shoe,

applying pressure to bring a portion only of the inner surface of the heel, as at its` margin, and said receiving1 surface into contact, and, While driving nails to attach the heelfto the shoe, bringing more ot these cooperatingsurtaces into contact, preferably at this time completing this contact and as a result ot the simultaneous action oi the heads `of the nails upon a contact member in the heel. Said heel is leest held initially against lateral expansion, so that it may he definitely located and pressure applied Without distortion Which will carry the heelopenings away trom the die-bloclr-openings, this holding effect preferably continuing until the attachingnails have entered the lieelloase, and then theheel is `treed for expansion, as by the action ot the nails, so that ,it may flatten toits final position.

In another aspect, a feature of the invention resides in a holding device which may be used in carrying out my improved method. IThis consists. ot a member pirovided with a heelreceiving depression, having `vvalls ot dill'erent heights respectively arranged tor contact with `dilierent periph eral portions o'la heel. `In the initial step of Apositioning and applying the clainping pressure. to the heel, the Walls ot' greatest height retain the heel against expansion, and themas the pressure continues to complete the engagement between the heel and receiving surface, the Walls ot less height allow the heel to. be treed and to erpainY assuming its final, flattened form.

In the accompanying drawing, Figure l illustrates in vertical section, talren upon the longitudinal axis of the shoe operated on, a machine equipped with my novel heel-holdingl device and generally arranged ior the performance ot my improve-d method otheel-attachment, the parts 1seing in the-relation for the application oft pressure: Fig. Zvis a transverse section through the heel and holder vFig. 3ds av longitudinal section similar to Fig. l., showing the `linal step ot attaclr Yment this invention is especially useful is illustrated at H in Fig. of the drawing. rlhis is in the form of a lift of rubber or other yieldable compound, which at its inner side is concave, and correspondingly convex at its outer tread-surface 12 At the peripheral edge, the inner surface has points of greatest normal upward curvature, or that existing before the heel is applied to the shoe, at the ends 14, 14 of the breast and at the extreme, central rear portion 16. Between these points, the edge curves downwardly to points 15 of minimum height. At the tread-surface of the heel are openings 18 to receive the attaching nails, and molded in the body of the heel, with their openings in alignment with the openings 18, are washers 20, or other contact members, as sheets of metal or dense fabric, for engagement by the heads of the nails. When the heel is applied, the curved body becomes flattened, so that the inner surface 10 is in substantial contact with the entire outer surface of the receiving base, while the tread-surface 12 of the heel is parallel thereto. The peripheral edge is then perpendicular to these surfaces 10 and 12.

Such heels have, as far as am aware, always been attached by hand, the workman positioning the heel upon the base, placing the nails in the openings 18, and then, still holding the heel in its symmetrical relation to the base, driving the nails to draw the heel, by the engagement of the nailheads with the washers, te its filial, flattened position. ln thus operating, no preliminary or clamping` pressure is applied. The didiculties already mentioned have stood in the way of machine-attachment of these concave heels, as this has been customarily practiced. Used in accordance with my invention, however, any heeling machine may be successfully employed for nailing such heels. Portions of an apparatus similar to that illustrated in Patent No. 1,157 ,688, Glidden, Getober 26, 1915, appear in the drawing, especially in Fig. 1. At is shown a die-block having` openings 32 to receive the drivers 34 mounted upon a reciprocatory plate 36. The shoe S, to the heelbase 22 of which a concave heel-lift H is to be applied, is placed upon a jack 38, arranged to swing from a receiving position at the front of the die-block to that illustrated in Fig. 1, in which the work is ready for the nailing operation. The jack and die-block have a relative movement toward and from each other, by virtue of which the shoe may be applied to the aclr and brought into position over the openings 32 during the period of separation, and then, as the two elements approach, pressure will be applied to clamp the heel H, supported upon the die, against the base 22, preventing lateral displacement and preparing the work for the driving of the nails, which is effected by the upward travel of the drivers 34. Nails N, having heads 24, are supported in the die-bloclr-openings upon the ends of the drivers, having been delivered manually or by a suitable loading mechanism, not illustrated.

Secured upon the upper side of the dieblock, with openings 40 in alinement with the block-openings 32, is a holder member 42, having in its upper face a heel-receiving depression 44, the bottom wall of which possesses a curvature substantially that of the surface 12 of the heel H. 46, which are shown as vertical, have portions of maximum height at 48, these corresponding to the sides of the heel at 15. The walls 46 are of minimum height at 50, or at the points corresponding to those designated upon the heel as 14 and, 16. As illustrated, the walls at 50 merge into the upper surface 52 of the member 42, thus becoming of zero height. Such a holder may conveniently be produced by casting, employing the heel with which it is to be used as a pattern.

In the performance of my improved method, the. heel H is placed in the depression 44, which substantially conforms to it,

the side walls of the depression at 48 furnishing abutments, which prevent'the lateral movement of the heel, while between the points 50, at the breast side and at each side of such point at the rear of the heel, the walls are of sulicient height to hold the heel aga-inst movement longitudinally wWhen the preliminary pressure is applied, it partially iiattens the heel, bringing its marginal portions into engagement with the base, as is illustrated in Figs. 1 and 2. The heel and shoe thus being held in proper relation, the drivers 34, upon each of which a nail is resting, rise and simultaneously carry the points of the nails through the heel-openings 18, and the alined openings of the washers 2O into the base. As this action continues, the nail-heads reach the washers, and by their engagement therewith exert pressure upon the heel to flatten it and, when fully driven, completing its contact with the base, as appears in Fig. 3. At the same time, this driver-action raises the heel out of the holder-depression free from the walls 46, so that it is permitted to expand laterally in the assumption of its final form, thus completing the operation.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. The method of attaching yieldable concave heels, which consists in relatively positioning a heel and the receiving surface of a shoe, applying pressure to bring a portion The side walls llt) only of the inner surface of the VVheel and said receiving surface into contact, driving nails to attach the heel to the shoe, and bringing more of the inner surface of the heel into contact with the receiving surface.

9,. The method of attaching yieldable concave heels, which consists in relatively positioning a heel and the receiving surface of a shoe, applying pressure to partially ilat ten the heel and bring the marginal portion only of its inner surface into contact with the receiving` surface, and simultaneously driving a plurality of nails to attach the heel to the shoe and to further iiatten the heel and complete the contact of its inner surface with the receiving surface. y

The method of attaching` yieldable concave heels each provided with a contact member, which consists in relatively positioning a. heel and the receiving surface of a shoe, applying pressure to bring a portion only of the inner surface of the heel and said receiving surface into contact, and simultaneously driving a plurality of headed nails through the contact member to attach the heel and by the engagement of the heads With said contact member to bring more of the inner surface into contact with the receiving surface. s

4;. rlhe method of attaching rubber heels, which consists in holding a vheel against lateral expansion, relatively positioning said heel and the receiving surface of a shoe, applying pressure to carry the heel and shoe toward each other, driving nails'to attach the heel, and freeing the previously held portion of said heel for lateral eX- pansion during the application of operating` pressure. Y
